Abstract

A bearing system for use in high speed rotating machinery, such as a turbocharger (14), wherein a shaft (12) is rotatably supported by a floating bearing cartridge ( 10) having axially spaced angular contact bearings (16, 18) each with a set of bearing balls (30) supported between inner and outer races (32, 34). The bearing cartridge includes an inner spacer sleeve (42) for axially spacing the inner bearing races, and a rotationally floating outer sleeve (46) having a pair of radially inwardly open grooves (52) for removably receiving snap-type retaining rings (54) which engage and axially space the outer bearing races. The axial dimension of the inner spacer sleeve is elongated slightly relative to an axial dimension defined between outboard faces of the installed retaining rings, thereby slightly unloading the sets of bearing balls from their respective outer bearing races. Such slight axial unloading enhances smooth- running operation with minimal bearing wear, while accommodating transient loads during operation.
